Could be extremely good tempo if you have already played that 5 mana rotate a bomb card. I suppose this is pending more support from future reveal cards? I think after rotation you have access so far to only 2 bombs? We will see what else gets revealed. So far playable-good, but not yet wow-factor.
EDIT: forgot we were a card reveal event today. Saw a handful of bomb cards. Bright side it is a fun looking archetype for warrior. Bomb Warrior
